MKU PA 23CM-1200W A – Power Amplifier

High power linear amplifier for the 23 cm Amateur Radio band

Our high-performance amplifier for the 23 cm amateur radio band achieves great performance, high efficiency and best linearity. In contrast to tube amplifiers, an LDMOS transistor with a supply voltage of only +50 V is used here. High-voltage transformers, preheating and annoying post-voices are a thing of the past! The amplifier can be mounted close to the antenna to avoid power losses due to long coaxial cables.
